It seems that this save either chose Evelyn when meeting Ashelander in her cave (and how you got to Quest State 4 [delivering Kaina's tea to Ashe]) OR you somehow reached state 4 without choosing, so the quest automatically chose; if Azyrran was recruited, flags.ASHE_SPEAR_CHOICE is 1, but if the PC learned of Evelyn's past, it would be a 2.
You can console command to change the flag to 1 if you want, but this doesn't seem to be a bug.
